Arianna went running for 0.75 hours and ran 5.55miles. What was her speed, in miles per hour, if Arianna ran at the same speed for her whole run?

Determine the units of the variable x in each of the following equations, and specify which rule you used to determine this. Do not solve for the numeric value of x. Show your work beneath the question, or on a separate sheet of paper. Example: 315 feet = (32)x² Rule #1: Both sides of the equal sign must have the same units. Rule #2: Values that are added or subtracted must have the same units. Rule #13: Argument of a trig function must be an angle. Rule #14: Argument of an inverse trig function must have no units. Rule #5: Exponents must have no units. x has units of seconds because of Rule # 1
